While oven is preheating, unwrap all the Hershey Hugs and set them aside.
Prepare a baking sheet lined with parchment paper.
Arrange the pretzels on the baking sheet.
Top each square pretzel with one Hershey's Hug. Make sure the hug is in the center of the pretzel to avoid spill over. Once all the hugs are in place, put the baking sheet in the oven for 3 minutes and 30 seconds or until hugs are slightly melted.
Remove the oven. Using a toothpick, gently jiggle the center of each hug to flood the chocolate on the pretzel.
Gently place one M&M in the center of each hug. Make sure to not press down or the chocolate may run over the pretzel. Repeat this step until all the hugs have M&Ms.
Place on a cooling rack to cool to room temperature or you can place them in the fridge to speed up the cooling process.
Package in your favorite airtight jar or tin for a cute gift or serve immediately and enjoy!
Notes
Oven times may vary. If your hug is not melted enough, heat for an additional 30 seconds.
